FineCoder Apps ("we", "our", or "us") operates the Length Pro mobile application (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App and the choices you have associated with that data.
The App itself does not require user registration or account creation, and we do not collect or store any personally identifiable information (PII) such as your name, email address, phone number, or precise location.
All calculation history, unit preferences, and custom settings (such as dark mode and fraction precision) are stored locally on your device and are never transmitted to our servers.
The App utilizes third-party services that may collect information used to identify your device for advertising, analytics, and app update purposes. These third-party service providers have their own privacy policies addressing how they use such information:
While the App does not explicitly use cookies, third-party libraries (such as Google AdMob) may use cookies, Advertising IDs (AAID), or anonymous device identifiers to collect information and serve ads tailored to your interests.
You can manage or opt-out of personalized advertising through your Android device settings by navigating to Settings > Google > Ads and resetting or opting out of Ads Personalization.
Our App does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we can take necessary actions.
We value your trust in using our App. Since all app data is stored locally on your device, your calculation history and preferences remain secure under your device's security system.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
If you have any questions or suggestions about our Privacy Policy, do not hesitate to contact us at: see Developer Page.
